ligg-lurning '.l`rays for Incnbators; and weh do declare the following to he a full, clear,

and exact description of the invention. such as will enable others skilled in the art to which it appertaiiis to inake and use the saine. reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in egg trays or turners for incubators.

The object of the invention is to provide such :i device having a capacity for turning in a body diti'erent sizes of eggs so that the eggs shall he substantially uniformly presented to the action of the temperature of the incubator.

lreeeding a detailed description of the invention, reference is inade to lheaeeoni p in ving drawings, of which- Figure- 1. is a top plan view of the egg tray with parts broken away. Fig. 2, is a horizontal .side elevation thereof. Fig. il. is a horizontal section on the line i ot' Vig.

l. Fir'. Ll. is an enlarged view ofthe dial h v means of which the extent of rotation ot' the rollers is determined. lvig. .'i. is a detail 'view of the gage by means of which the rollers are. selected. Fig. is a seeiioiial view oi' one side of the device on the line f z ot' Fig. 1. Fig. 7, is an end view of a corner of the tray.

In a detail description of the invention. similar reference characters indirate eorrespondingr parts.

The supporting frame consists of side and 'end strips l united at their ends by bottoni tirare strips 2 which tie the side and end (hi one `ide which su ports the journals ofthe rollers -l -on one sii e of the frame, said journals twiner also supported in the side strip 1 at that side ofthe frame. The journals of the other ends ofthe rollers are dropped into openings in the other side strip l. This may he done whenever it is necessary to change the rollers to suit different sixes of eggs. It will he understood', however, that all the eggs sup ported between each pair of rollers of approxiinately the same size, should 'also be of approximately the same size. Then it. be-

comes necessary to place rollers of different sizes in the tray, owing to the di tterent size.`- of eggs, it is necessary that the eggs supported on a roller of smaller diameter which is adiacent to one of larger diameter,

be prevented from Corning iii eontatt with 65.

the larger roller. This is accom lished by placing a rod 5 arallel with and adjacent to said larger rol er, as seen in Fig. 1. This rod 5 has its ends bent; and inserted in any two of the openings 6 arranged in the upper 70` .surface ot the side strips l, and it niay be removed to any point. where its use may be required.

The bottoni of the tray is iiiclosed by a wire screen 7, the purpose of which is to catch the chickens :is they are liberated from the eggs through the action of the incubator.v The eggs-supporting rollers have sprocket wheels 8 on their ends `which are of uniform diameter, and around these sprocket wheels )asses an endless chain 9, a common meansl or rotating the rollers in a body. In order to maintain the lower run of the chain in proper engagement with the sprocket wheels. a .slide 1t) is provided which is iii- 85 sorted at one end of the tray along the bottoni strip L. and beneath the chain. See Figs. Z and sary to remove one or more rollers to be replaced by other rollers of ditterent. size or 9C' sizes. the strip l0 may be removed by drawing' it through the opening 1l at one end of the tray. The openingi ll is closed by a door 2l. and the slide or .strip 10 is thus prevented- I'roni movingF out of its position below the 95 .-liain while the tray is in use. The roller at au evti'eioo end of the tray has its journal niaih- .square and extended through the side ol' the traine as at'. 1;. .such square end being .adapted to receivia lt'ev (not shown) by 100 nii-ans of whit-li .said roller may be rotated and therewith the other rollers through the eliain *.l. Fitting over said extended journal is :in indii-ator in the fooi of a dial 13 which is tixed in its position and bears a zero mark.

1H designates a pointer which is fixed to the. end 1:2 of the roller and is movable over the t'aee of the dial to and from the zero niark when :i eoinplete rotation of the rollers is made.

t-l designates a rotatable piece containing a sight openiuy t5 through which the tigures Whenever it becomes neces- 12 in rotzitei:
